Dinosaur teeth give glimpse of early Earth’s climate

University of Göttingen
Peer-Reviewed Publication

A previously untapped source of data sheds new light on the climate of the early Earth: fossilized dinosaur teeth show that the atmosphere during the Mesozoic era, between 252 and 66 million years ago, contained far more carbon dioxide than it does today. An international research team at the Universities of Göttingen, Mainz and Bochum made this discovery by analysing oxygen isotopes in tooth enamel. They used a newly developed method that opens up opportunities for research into the Earth's climate history. In addition, the researchers found that total photosynthesis from plants around the world was twice as high as it is today. This probably contributed to the dynamic climate during the time of the dinosaurs. The results were published in the journal PNAS.

New study reveals the role of subtle changes of Northern Westerlies in the East Asian monsoon variability

Xi'an Jiaotong University, Institute of Global Environmental Change
Peer-Reviewed Publication

The research highlights how changes in the Northern Westerlies have influenced East Asian summer monsoon precipitation isotope during past abrupt climate events, providing insights into understanding high- and low-latitude teleconnections.

The East Asian summer monsoon (EASM), which sustains the livelihoods of billions of people, is a vast and complex climate system. While its variability during glacial periods has been closely linked to abrupt climate events such as the Dansgaard-Oeschger (DO) events, the role of the Northern Westerlies in modulating EASM moisture transport and isotopic compositions remains poorly understood.

Unicellular cyanobacterium UCYN-B significantly contributes to global oceanic nitrogen fixation

Science China Press
Peer-Reviewed Publication

A study in National Science Review reports systematic observations of diazotroph abundance, community structure, and N₂ fixation rates in the western North Pacific. Using generalized additive models, the team characterized ecological niches of key cyanobacterial diazotrophs and quantified UCYN-B’s contribution to global N₂ fixation. The findings highlight UCYN-B’s pivotal role in marine N₂ fixation and provide new insights into ocean nitrogen cycle and productivity under climate change.

From the atmosphere to the abyss: Iron's role in Earth's climate history

University of Hawaii at Manoa
Peer-Reviewed Publication

A new study published by researchers at the University of Hawai‘i at Mānoa sheds light on the critical role of iron in Earth’s climate history, revealing how its sources in the South Pacific Ocean have shifted over the past 93 million years. This groundbreaking research, based on the analysis of deep-sea sediment cores, provides crucial insights into the interplay between iron, marine life, and atmospheric carbon dioxide levels.

Scientists reveal how microbes collaborate to consume potent greenhouse gas

University of Southern California
Peer-Reviewed Publication

Scientists discovered deep-sea microbes using bio-electrical conductors to collaborate and consume methane, a potent greenhouse gas, before it escapes into the atmosphere. This is the first direct evidence of how these natural marine microbial partners [DJ1] transmit electricity between cells. Understanding how these electric microbial partnerships work could inspire new approaches to reduce greenhouse gas emissions.

Study finds wide variation in Amazon’s response to degradation and climate change

Yale University
Peer-Reviewed Publication

The research by Yale School of the Environment scientists highlights the need to reduce the “hammer” of human impact and deforestation rather than focus on an all-encompassing climatic tipping point.

Sea-level projections from the 1990s were spot on, Tulane study says

Tulane University
Peer-Reviewed Publication

Tulane researchers found that mid-1990s climate projections of sea-level rise were remarkably accurate when compared with 30 years of satellite data. The 1996 IPCC report predicted about 8 cm of rise, close to the 9 cm observed, though it underestimated ice-sheet contributions. The study highlights both the credibility of climate models and the importance of continued monitoring. Researchers stress the need for region-specific projections, especially for vulnerable coastal areas like south Louisiana, where sea-level rise varies widely.
